【摘要】：随着现代工业对机械设备及机械传动系统的要求越来越高,世界传动系统研究的重点逐渐向高速、重载、长寿命、低成本等方面发展,超环面行星蜗杆传动这一新型传动应运而生,成为近年来国内外学者研究的热点。本文主要研究了圆柱齿超环面行星蜗杆传动的强度计算分析,完成了以下工作: 推导出了圆柱齿超环面行星蜗杆传动的接触强度计算公式,通过四因素三水平的正交试验,研究出接触应力大小的主要影响因素及影响规律,并基于以上研究,确定中心距为接触强度设计参数,给出超环面行星蜗杆传动的接触强度计算方法。推导出圆柱齿超环面行星蜗杆传动的行星轮齿及内齿圈齿的弯曲强度计算公式,分别通过正交试验,研究出其弯曲应力大小的影响因素及影响规律,基于以上研究,确定圆柱滚子的滚针轴承内径及内齿圈螺旋齿厚分别为圆柱滚子及内齿圈的弯曲强度设计参数,通过选定合适的圆柱滚子半径系数来完成该机构的弯曲强度设计。建立了该减速器各个部件的精确三维实体模型。借助有限元分析软件ABAQUS对此模型进行数值计算,分别得到了中心蜗杆、行星轮、超环面内齿圈的应力云图。通过分析得到中心蜗杆、行星轮、内齿圈接触面上的接触应力和圆柱滚子齿及超环面内齿圈螺旋齿的弯曲应力,分析结果验证了接触强度及弯曲强度计算公式的正确及设计方法的正确性。
[Abstract]:With the development of modern industry of machinery and mechanical transmission system of the increasingly high demand, focus on the transmission system of the world gradually to the high speed, heavy load, long life, low cost and other aspects of development, the toroidal drive is a new drive came into being, has become the focus of domestic and foreign scholars in recent years. This paper mainly studies the calculation and analysis cylindrical teeth toroidal drive strength, complete the following work:
A formula is derived to calculate the contact strength of the cylindrical gear of the toroidal drive, through the orthogonal test of four factors and three levels of contact, main influence factors and influence laws of force, and based on the above research, determine the center distance of the contact strength design parameters for the contact strength of toroidal drive method.
The calculation formula of flexural strength of planetary gear and inner gear are derived in cylindrical teeth toroidal drive, respectively through orthogonal test, study the bending influence factors and influence laws of force, based on the above research, determine the needle bearing diameter and the inner ring gear helical cylindrical roller thickness were bending strength the design parameters of cylindrical roller and ring gear, by selecting the appropriate radius coefficient of cylindrical roller to complete the bending strength design of the institution.
A 3D solid model of the reducer parts. This model is calculated by using finite element analysis software ABAQUS, obtained center worm, planetary gear, stress nephogram of toroidal ring gear. The center of the worm, through the analysis of planetary gear, internal gear contact should be bent force and cylindrical roller teeth toroidal ring gear with helical teeth, the analysis results verified the correct design method and calculation formula of contact strength and bending strength.
